Update from Thomson Reuters:
Q: Why is the Times Cited count different in some records in the two different versions of Web of Science?
A: Users who navigate between the two versions may note differences in data that in some instances impact citation counts and H-indexes.
We have identified errors affecting a subset of records that were uploaded within the last week. We have isolated the impacted records and are diligently working to rectify the problem. We expect to have these data corrected within approximately 2 weeks.
In most instances in which the two versions of Web of Knowledge yield different citation counts, it does not indicate error but instead reflects enhancements made to the application. The new platform functions as the same citation-based search and discovery tool, but we’ve improved the underlying architecture. Please keep in mind that citation counts are dynamic. While the majority of citation counts between the two versions of Web of Knowledge are the same, a small number will be different as a result of new methods for record unification.
